My apologies if this information is already available, but is there a walkthrough available for changing the nozzles on the Pro2 series printers, as well as calibrating the nozzle heights (between the two extruders) afterwards to account for any difference in the length of the new nozzle.

So there is no other way to replace the nozzle without removing the entire extruder and realign everything from the throat tube down? I know you were being "not like every other manufacturer" but this seems overboard. Cold removal of these parts just sounds wrong when most manufacturers recommend the nozzle be heated.

You must heat the nozzle assembly and retighten or experience a leaking nozzle body. Trust me, mine leaked from the factory and its caused many problems that have not been resolved. Broken coupling, loose belt, clogged nozzles. Still experiencing layer shifting on prints and cant use the printer.
